Calculate the exit velocity and flame length of a jet fire of 20 kg/s mass flow caused inside a high pressure propane pipeline. The following data are available: Initial pressure of the pipeline, Ps : 10 MPa Wind velocity, uw : 5 m/s Specific heat capacity, Cp : 1.7 kJ/kgK 2 Ambient temperature, Ta : 278 K Ambient pressure, Pa : 0.1 Mpa Molecular weight of propane, Wg : 0.0441 kg/mol Molecular weight of air, Wair : 0.029 kg/mol Angel between hole axis/wind axis, jv : 80 You may consider supersonic flow. Please list all the steps properly and then try to solve the problem.
